i have these. i am generally a comfortable 33 also. i bot the 30 to allow for stretch, and while intially i found them quite painful, they are now a good deal more relaxed, but still very tailored. i will say, however, that i would surely have switched to 32, as the slim guy fit works a little better when its less tight, with more draping and less pronouncement of the genitals.
Thanks for the response- would you compare your fit to something like this?
Because I think that this fit looks ideal!
